Well,the article is ridiculous.Author says that just because safe ivermectin levels cannot be stretched to levels of IC50 in humans, as the AU in vitro study did,then it follows that "Ivermectin alone not useful in treating COVID-19". The subject and title should be about the practical uselessness to humans of the AU study findings rather than stating that ivermectin itself is useless against covid. Idk, am i not understanding her assertions peoperly, because it sounds like faulty logic to me.
